The sorption-enhanced chemical-looping steam reforming (SE-CLSR) of liquid biofuels, such as bioethanol, biodiesel, and glycerol, emerges as an innovative technology for sustainable hydrogen production that effectively integrates in situ CO 2 capture via solid sorbents with redox cycling. This paper discusses recent advances, challenges, and future perspectives on the SE-CLSR process in enhancing hydrogen production and CO 2 capture. Key issues include system design, catalysts and sorbents used, and environmental and economic analysis for industrial applications. Moreover, the review evaluates recent SE-CLSR performance achievements and proposes strategies integrating in situ CO 2 capture and utilization (CCU) by methane dry reforming (MDR), simultaneously creating high-purity hydrogen and syngas. Future research should focus on developing novel catalysts and sorbents, including a bifunctional material (BFM) for catalytic reforming reactions with CCU, optimizing SE-CLSR design, reducing the cost of CCU, and establishing the models for large-scale SE-CLSR implementation.
